Способ получения серной кислоты окислением сернистой кислоты кислородом в присутствии оксидов азота, отличающийся тем, что, с целью утилизации сернистого ангидрида и использования его для получения серной кислоты из техногенных источников, в которых применение других способов экономически нецелесообразно, а также с целью уменьшения теплового загрязнения атмосферы, процесс ведут при температуре 30 - 120oС и давлении 1 - 2 атм, оптимальные условия поддерживают, регулируя концентрацию сернистой кислоты, поступающей на окисление, скоростью реакции управляют посредством изменения концентрации компонентов газообразной фазы внутри реактора.A method for producing sulfuric acid by oxidation of sulfur dioxide with oxygen in the presence of nitrogen oxides, characterized in that, in order to utilize sulfur dioxide and use it to obtain sulfuric acid from industrial sources in which the use of other methods is not economically feasible, and also to reduce thermal pollution of the atmosphere , the process is conducted at a temperature of 30 - 120 o C and a pressure of 1 - 2 bar, the optimum conditions are maintained by regulating the concentration of sulfurous acid entering the oxidation rate p action controlled by changing the concentration of the components of the gaseous phase within the reactor.
